react+canvas实现横跨整个页面的动态的波浪线（贝塞尔曲线）

本来写这个特效我打算用css实现的，结果是一波三折，我太难了，最终没能用css实现，转战了canvas来实现。来吧先看效果图
在这里插入图片描述
当然这个图的波浪高度、频率、位置、速度都是可调的，请根据自己的需求调整，如果你讲波浪什么的调大一下还有有摆动的效果哦。

以下是完整代码

import React, { useEffect, useRef } from 'react';
import classNames from 'classnames';
const WaveAnimation = () => {
  const canvasRef = useRef<HTMLCanvasElement | null>(null);

  useEffect(() => {
    const canvas = canvasRef.current;
    if (canvas) {
      const ctx = canvas.getContext('2d');
      console.log('ctx', ctx);
      if (ctx) {
        const amplitude = 60;
        const frequency = 0.006;
        let phase = 0;
        const centerY = canvas.height / 2;
        const startX = -10;
        const speed = 0.2;
        const lineColor = 'rgba(255, 255, 255, 0.1)';

        const animate = () => {
          ctx.clearRect(0, 0, canvas.width, canvas.height);
          ctx.beginPath();
          ctx.moveTo(startX, centerY);

          for (let x = startX; x < canvas.width; x++) {
            const y = centerY + amplitude * Math.sin(frequency * x + phase);
            ctx.lineTo(x, y);
          }

          ctx.strokeStyle = lineColor;
          ctx.lineWidth = 10;
          ctx.stroke();

          phase -= speed;

          requestAnimationFrame(animate);
        };

        animate();
      }
    }
  }, []);

  return (
    <div className="wave-animation">
      <canvas ref={canvasRef} width="3000" height="300"></canvas>
    </div>
  );
};

export default WaveAnimation;
